Buried Treasure? Overlooked and Newly Discovered Evolutionary Contributions to Human Brain Diseases

open access: yesAnnals of Neurology, EarlyView.
Recapitulative schema of different exploratory levels of the evolutionary impact on human neurological diseases. Clinical neuroscience focuses on the mechanisms of brain function, but this approach falls short of insights into how the central nervous system (CNS) evolved, both in health and disease.

What does it mean? Translating anatomical language to engage public audiences

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The language of anatomy, with its roots in Ancient Greek and Roman languages, is complex and unfamiliar to many. Its complexity creates a significant barrier to public knowledge and understanding of anatomy—many members of the public find themselves asking “what does it mean?”, and this can manifest as poor health literacy and outcomes.

Learning Contextual Reward Expectations for Value Adaptation [PDF]

open access: yes, 2018
Substantial evidence indicates that subjective value is adapted to the statistics of reward expected within a given temporal context. However, how these contextual expectations are learned is poorly understood.
